| (54) | MECHANISMS FOR MOTOR CONTROL ADJUSTMENTS OF A MOTORIZED SURGICAL INSTRUMENT |
| (57) A surgical instrument is disclosed including an end effector, a shaft, and a housing.
The end effector includes an RFID tag configured to store end effector information.
The shaft includes a first RFID scanner and a second RFID tag configured to store
shaft information. The first RFID scanner is configured to detect the first RFID tag
in a first attached configuration. The housing includes a second RFID scanner configured
to detect the second RFID tag in a second attached configuration, a motor configured
to apply a load to the end effector, and a control circuit. The control circuit is
configured to receive input from the first RFID scanner indicative of the end effector
information, receive input from the second RFID scanner indicative of the shaft information,
and adjust at least one parameter of operation of the motor based on the end effector
information and the shaft information.
